Winter temperatures are soaring in the Arctic for the fourth winter in a row. The heat, accompanied by moist air, is entering the Arctic not only through the sector of the North Atlantic Ocean that lies between Greenland and Europe, as it has done in previous years, but is also coming from the North Pacific through the Bering Strait.
“We have seen winter warming events before, but they’re becoming more frequent and more intense,” said Alek Petty, a sea ice researcher at NASA’s Goddard Space FlightCenter in Greenbelt, Maryland.
Scientists are waiting to see how much this heat wave will impact the wintertime sea ice maximum extent, which has been shrinking in the past decades and has hit record lows each of the past three years. The sea ice levels are already at record lows or near-record lows in several areas of the Arctic. Another exceptional event this winter is the opening up of the sea ice cover north of Greenland, releasing heat from the ocean to the atmosphere and making the sea ice more vulnerable to further melting.
“This is a region where we have the thickest multi-year sea ice and expect it to not be mobile, to be resilient,” Petty said. “But now this ice is moving pretty quickly, pushed by strong southerly winds and probably affected by the warm temperatures, too.”

As the mean global temperature continues to rise, the arctic ice caps continue to melt. What are scientist planning to do about it? Here's a hint: it involves 10 million sea water pumps.

Scientists Have Announced a Plan to 'Refreeze' the Arctic - and It'sWild
http://www.sciencealert.com/scientists-have-announced-a-plan-to-refreeze-the-arctic-and-it-s-wild
"Desperate times call for desperate measures, and with temperatures near the North Pole hitting an unheard-of 20°C (36°F) warmer than average last year, things in the Arctic are undeniably grim right now. But rather than sit by and watch as the sea ice disappears from the region at an unprecedented rate, scientists have hatched a crazy plan to 'refreeze' the Arctic, by installing some 10 million wind-powered pumps over the ice cap to spray sea water over the surface and replenish the sea ice."
Arctic ice management
http://onlinelibrary.wiley.com/doi/10.1002/2016EF000410/full
"As the Earth's climate has changed, Arctic sea ice extent has decreased drastically. It is likely that the late-summer Arctic will be ice-free as soon as the 2030s. This loss of sea ice represents one of the most severe positive feedbacks in the climate system, as sunlight that would otherwise be reflected by sea ice is absorbed by open ocean. It is unlikely that CO2 levels and mean temperatures can be decreased in time to prevent this loss, so restoring sea ice artificially is an imperative."
How a giant space umbrella could stop global warming
http://www.bbc.com/future/story/20160425-how-a-giant-space-umbrella-could-stop-global-warming
"The race to find a solution to a rapidly warming world is one of the most pressing challenges facing our planet. One proposal to try to halt this warming is literally out-of-this-world: a giant, space-based sunshade. We're already modifying our climate by accident, so why not do it by deliberate geoengineering? It's a radical idea, and it just might just work. Reducing the amount of light reaching our planet could cool the Earth quickly, even with rising carbon dioxide levels."

Coast guard

A coast guard or coastguard is a maritime security organization of a particular country. The term implies widely different responsibilities in different countries, from being a heavily armed military force with customs and security duties to being a volunteer organization tasked with search and rescue functions and lacking any law enforcement powers. However, a typical coast guard's functions are distinct from typical functions of both the navy (a pure military force) and a transportation police (a civilian law enforcement agency).

Each Water Guard station was issued with Manby's Mortar which was invented by Captain George William Manby in 1808. The mortar fired a shot with a line attached from the shore to the wrecked ship and was used for many years up and down the coastline. This began the process in which the Coastguard assumed a life saving role. In 1821 a committee of inquiry recommended that responsibility for the Preventative Water Guard be transferred to the Board of Customs. The Treasury agreed and in a Minute dated 15 January 1822, directed that the preventative services, which consisted of the Preventative Water Guard, cruisers, and Riding Officers should be placed under the authority of the Board of Customs and in future should be named the Coast Guard. In 1845 the Coastguard was subordinated to the Admiralty.

A spaceflight typically begins with a rocketlaunch, which provides the initial thrust to overcome the force of gravity and propels the spacecraft from the surface of the Earth. Once in space, the motion of a spacecraft—both when unpropelled and when under propulsion—is covered by the area of study called astrodynamics. Some spacecraft remain in space indefinitely, some disintegrate during atmospheric reentry, and others reach a planetary or lunar surface for landing or impact.

Goddard Space Flight Center

The Goddard Space Flight Center (GSFC) is a major NASA space research laboratory established on May 1, 1959 as NASA's first space flight center. GSFC employs approximately 10,000 civil servants and contractors, and is located approximately 6.5 miles (10.5km) northeast of Washington, D.C. in Greenbelt, Maryland, USA. GSFC, one of ten major NASA field centers, is named in recognition of Dr. Robert H. Goddard (1882–1945), the pioneer of modern rocket propulsion in the United States.

GSFC is the largest combined organization of scientists and engineers in the United States dedicated to increasing knowledge of the Earth, the Solar System, and the Universe via observations from space. GSFC is a major U.S. laboratory for developing and operating unmanned scientific spacecraft. GSFC conducts scientific investigation, development and operation of space systems, and development of related technologies. Goddard scientists can develop and support a mission, and Goddard engineers and technicians can design and build the spacecraft for that mission. Goddard scientist John C. Mather shared the 2006 Nobel Prize in Physics for his work on COBE.

Scientists Have Announced a Plan to 'Refreeze' the Arctic - and It'sWild
http://www.sciencealert.com/scientists-have-announced-a-plan-to-refreeze-the-arctic-and-it-s-wild
"Desperate times call for desperate measures, and with temperatures near the North Pole hitting an unheard-of 20°C (36°F) warmer than average last year, things in the Arctic are undeniably grim right now. But rather than sit by and watch as the sea ice disappears from the region at an unprecedented rate, scientists have hatched a crazy plan to 'refreeze' the Arctic, by installing some 10 million wind-powered pumps over the ice cap to spray sea water over the surface and replenish the sea ice."
Arctic ice management
http://onlinelibrary.wiley.com/doi/10.1002/2016EF000410/full
"As the Earth's climate has changed, Arctic sea ice extent has decreased drastically. It is likely that the late-summer Arctic will be ice-free as soon as the 2030s. This loss of sea ice represents one of the most severe positive feedbacks in the climate system, as sunlight that would otherwise be reflected by sea ice is absorbed by open ocean. It is unlikely that CO2 levels and mean temperatures can be decreased in time to prevent this loss, so restoring sea ice artificially is an imperative."
How a giant space umbrella could stop global warming
http://www.bbc.com/future/story/20160425-how-a-giant-space-umbrella-could-stop-global-warming
"The race to find a solution to a rapidly warming world is one of the most pressing challenges facing our planet. One proposal to try to halt this warming is literally out-of-this-world: a giant, space-based sunshade. We're already modifying our climate by accident, so why not do it by deliberate geoengineering? It's a radical idea, and it just might just work. Reducing the amount of light reaching our planet could cool the Earth quickly, even with rising carbon dioxide levels."

Journey to the Arctic - TechKnow

The Arctic is warming up at twice the rate of the rest of the globe. Summer sea ice has receded by almost 25 percent since 1979, with the sea change becoming ever more apparent and Arctic-native animals now visibly struggling in their prolonged search for shelter, ice and food.
Offshore oil exploration and increased tourism have also contributed to the speed at which environmental changes are occurring in the Arctic, with the fear of an ice-free summer on the horizon looming over the fate of the area.
These changes have also been spotted on land, with melting permafrost causing entire patches of land and man-made structures to sink as the earth softens.

In the Arctic Seas,
Francis MCCLINTOCK (1819 - 1907)
In 1857, Lady Jane Franklin, the wife of Sir John Franklin, who went missing with his entire crew during his 1845 expedition to discover the Northwest Passage, commissioned CaptainFrancis McClintock to investigate what had happened to the expedition, and purchased for him the small steam yacht known as the 'Fox'. This is McClintock's own account of the two year voyage of the 'Fox'. Following an initially unsuccessful attempt to cross the Davis Strait, the 'Fox' was forced to spend the first winter trapped in the sea-ice off the coast of Greenland. After the next year's thaw, McClintock eventually reached the islands of the Canadian Arctic, where an ext...

The Arctic is warming up at twice the rate of the rest of the globe. Summer sea ice has receded by almost 25 percent since 1979, with the sea change becoming ever more apparent and Arctic-native animals now visibly struggling in their prolonged search for shelter, ice and food.
Offshore oil exploration and increased tourism have also contributed to the speed at which environmental changes are occurring in the Arctic, with the fear of an ice-free summer on the horizon looming over the fate of the area.
These changes have also been spotted on land, with melting permafrost causing entire patches of land and man-made structures to sink as the earth softens.
Proximity to land and resources also presents a challenge, not only in times of emergency on the water, but also in executing the research required to understand and attempt to combat the effects of global warming on the Arctic. This is where the Polar-class icebreakers factor in.
The United States owns only two icebreakers that are able to breach the density of ice formations the Arctic is known for. Weighing it at 16,000 tonnes and with the abilitiy to reach 30,000 horsepower, they are a force to be reckoned with on the open seas.
These vessels are used not only as a coast guard, but also to aide in sceintific studies. Missions often include unmanned vehicles - a safety precaution - including drones and others that explore not only the view from the air, but also what is happening in the water and life under the ice.
Levels of carbon dioxide in the air and the sea, water salinity, temperature, oxygen and chlorophyll blooms - a potentially dangerous situation where algae multiplies and decomposes on the surface of the water, using up oxygen resources from the rest of the sealife - are all deliverables that can be quantified using the unmanned vehicles.
Scientists from the Arctic Domain Awarness Centre at the University of Alaska Anchorage are also working on an 'isotope sniffer' amongst other experiments and unmanned 'drones'. A snout hangs out from the bow of a Polar-class icebreaker as a means of atmospheric sampling, and feeds the information down to isotope analysers below deck, in seconds-long intervals.
The ultimate vision is to understand the effects of potentially environmentally-damaging activity, such as offshore rigging by the Shell oil company, creating technology that can accurately register important data in extreme temperatures and conditions - 'guardians' of the water - without endangering the lives of crew members.

http://en.wikipedia.org/wiki/Arctic
The Arctic (/ˈɑrktɪk/ or /ˈɑrtɪk/) is a polar region located at the northernmost part of the Earth. The Arctic consists of the Arctic Ocean and parts of Alaska (United States), Canada, Finland, Greenland (Denmark), Iceland, Norway, Russia, and Sweden. The Arctic region consists of a vast ocean with a seasonally varying ice cover, surrounded by treeless permafrost. The area can be defined as north of the Arctic Circle (66° 33'N), the approximate limit of the midnight sun and the polar night. Alternatively, it can be defined as the region where the average temperature for the warmest month (July) is below 10 °C (50 °F); the northernmost tree line roughly follows the isotherm at the boundary of this region.
Socially and politically, the Arctic region includes the northern territories of the eight Arctic states, although by natural science definitions much of this territory is considered subarctic. The Arctic region is a unique area among Earth's ecosystems. The cultures in the region and the Arctic indigenous peoples have adapted to its cold and extreme conditions. In recent years the extent of the sea ice has declined. Life in the Arctic includes organisms living in the ice, zooplankton and phytoplankton, fish and marine mammals, birds, land animals, plants and human societies...
The Arctic's climate is characterized by cold winters and cool summers. Precipitation mostly comes in the form of snow. The Arctic's annual precipitation is low, with most of the area receiving less than 50 cm (20 in). High winds often stir up snow, creating the illusion of continuous snowfall. Average winter temperatures can be as low as −40 °C (−40 °F), and the coldest recorded temperature is approximately −68 °C (−90 °F). Coastal Arctic climates are moderated by oceanic influences, having generally warmer temperatures and heavier snowfalls than the colder and drier interior areas. The Arctic is affected by current global warming, leading to Arctic sea ice shrinkage and Arctic methane release.
Due to the poleward migration of the planet's isotherms (about 35 mi (56 km) per decade during the past 30 years as a consequence of global warming), the Arctic region (as defined by tree line and temperature) is currently shrinking. Perhaps the most spectacular result of Arctic shrinkage is sea ice loss. There is a large variance in predictions of Arctic sea ice loss, with models showing near-complete to complete loss in September from 2040 to some time well beyond 2100. About half of the analyzed models show near-complete to complete sea ice loss in September by the year 2100...

The Military Sealift Command (MSC) is a United States Navy organization that controls most of the replenishment and military transport ships of the Navy. It first came into existence on 9 July 1949 when the Military Sea Transportation Service (MSTS) became solely responsible for the Department of Defense's ocean transport needs. The MSTS was renamed the Military Sealift Command in 1970.
Military Sealift Command ships are civilian manned, and are referred to be as being in service, rather than in commission. Some, owned by the United States government, have the prefix USNS, standing for United States Naval Ship, whilst others, on charter or equivalent, are simply the normal merchant MV, SS, or GTS. Their hull numbers have the prefix T- in addition to the normal hull number that an equivalent commissioned ship in the USN would have.
Four programs comprise Military Sealift Command: Sealift, Naval Fleet Auxiliary Force (NFAF), Special Mission, and Prepositioning. The Sealift program provides the bulk of the MSC's supply-carrying operation and operates tankers for fuel transport and dry-cargo ships that transport equipment, vehicles, helicopters, ammunition, and supplies. The NFAF's role is to directly replenish ships that are underway at sea, enabling them to deploy for long periods of time without having to come to port. The Special Mission program operates vessels for unique military and federal government tasks, such as submarine support and missile flight data collection and tracking. The Prepositioning program sustains the US military's forward presence strategy by deploying supply ships in key areas prior to actual need...

http://en.wikipedia.org/wiki/Arctic_warfare
Arctic warfare or winter warfare is a term used to describe armed conflict that takes place in an exceptionally cold weather, usually in snowy and icy terrain, sometimes on ice-covered bodies of water. One must note the distinction between alpine and Arctic warfare - Arctic war does not always take place in mountainous terrain, and mountain warfare does not always take place in the cold.
The best recorded cold winter battles have taken place in northern and eastern Europe.
In 1242, the Teutonic Order lost the Battle of the Ice on Lake Peipus to Novgorod. In 1520, the decisive Battle of Bogesund between Sweden and Denmark occurred on the ice of lake Åsunden.
Sweden and Denmark fought several wars during the 16th and 17th centuries. As a great deal of Denmark consists of islands, it was usually safe from invasion, but in January 1658, most of the Danish waters froze. Charles X Gustav of Sweden led his army across the ice of the Belts to besiege Copenhagen. The war ended with the treaty of Roskilde, a treaty very favourable to the Swedish.
During the Great Northern War, Swedish kingCharles XII set off to invade Moscow, but was eventually defeated at the battle of Poltava after being weakened by cold weather and scorched earth tactics. Sweden suffered more casualties during the same war as Carl Gustaf Armfeldt with 6000 men tried to invade Trondheim, and 3000 of them died in a blizzard on a snowy mountain named Öjfjället.
During the Finnish War, the Russian army unexpectedly crossed the frozen Gulf of Bothnia from Finland to the Åland Islands and, by 19 March 1809, reached the Swedish shore within 70 km from the Swedish capital, Stockholm. This daring manoeuvre decided the outcome of the war.
Another famous example is the use of ski troops by the Finnish Army during the Winter War and the subsequent Continuation War, where the numerically dominant Soviet forces had a hard time fighting mobile ski soldiers.
In OperationBarbarossa in 1941, both Russian and German soldiers had to endure terrible conditions during the Russian winter. The German-Finnish joint offensive against Murmansk (Operation Silver Fox) in 1941 saw heavy fighting in the Arctic environment. Subsequently the Petsamo-Kirkenes Operation conducted by the Red Army against the Wehrmacht in 1944 in northern Finland and Norway drove the Germans out of there. In theLapland War, Finland turned against Nazi Germany under the Soviet Union's pressure, their former cobelligerents. While use of ski infantry was prolific in the Red Army, Germany formed only one division for movement on skis.
During Operation Zitronella in World War II, German and Allied troops fought over control of the island of Spitsbergen. This marks the highest latitude at which a land battle has ever been fought. However, given the extreme conditions, the German and Allied troops were at times compelled to assist each other to survive.
Operation Rösselsprung and Operation Wunderland were Arctic naval battles in World War II...
Arctic warfare is very dependent on equipment. For survival, troops need warm clothing and footwear, extra nutritious food, white camouflage, tents with sleeping bags, heaters and fuel.
Weapons can be fitted with an arctic trigger which permits firing while wearing heavy mittens.
Individual mobility can be increased by skis, cleats, and snowshoes.
Motorized vehicles are often unfit to stand freezing temperatures. Special procedures can be used to ensure they perform in the cold, such as running them continuously or starting them at regular intervals. Studded tires or tire chains are useful equipment for maintaining traction of wheeled vehicles. It is also possible to design special vehicles for operation specifically in arctic conditions, such as the Sisu Nasu, BvS 10, M29 Weasel or Aerosani...

NASA Studies an Unusual Arctic Warming Event

Winter temperatures are soaring in the Arctic for the fourth winter in a row. The heat, accompanied by moist air, is entering the Arctic not only through the sector of the North Atlantic Ocean that lies between Greenland and Europe, as it has done in previous years, but is also coming from the North Pacific through the Bering Strait.
“We have seen winter warming events before, but they’re becoming more frequent and more intense,” said Alek Petty, a sea ice researcher at NASA’s Goddard Space FlightCenter in Greenbelt, Maryland.
Scientists are waiting to see how much this heat wave will impact the wintertime sea ice maximum extent, which has been shrinking in the past decades and has hit record lows each of the past three years. The sea ice levels are already at record lows or near-record lows in several areas of the Arctic. Another exceptional event this winter is the opening up of the sea ice cover north of Greenland, releasing heat from the ocean to the atmosphere and making the sea ice more vulnerable to further melting.
“This is a region where we have the thickest multi-year sea ice and expect it to not be mobile, to be resilient,” Petty said. “But now this ice is moving pretty quickly, pushed by strong southerly winds and probably affected by the warm temperatures, too.”

Older Arctic Sea Ice Disappearing

Arctic sea ice has not only been shrinking in surface area in recent years, it’s becoming younger and thinner as well. In this animation, where the ice cover almost looks gelatinous as it pulses through the seasons, cryospheric scientist Dr. Walt Meier of NASA Goddard Space Flight Center describes how the sea ice has undergone fundamental changes during the era of satellite measurements.
Editor’s note: This visualization incorrectly identifies the oldest ice as being 5+ years old, when it would be more accurate to say 4+ years old.

Scientists Have Announced a Plan to 'Refreeze' the Arctic - and It'sWild
http://www.sciencealert.com/scientists-have-announced-a-plan-to-refreeze-the-arctic-and-it-s-wild
"Desperate times call for desperate measures, and with temperatures near the North Pole hitting an unheard-of 20°C (36°F) warmer than average last year, things in the Arctic are undeniably grim right now. But rather than sit by and watch as the sea ice disappears from the region at an unprecedented rate, scientists have hatched a crazy plan to 'refreeze' the Arctic, by installing some 10 million wind-powered pumps over the ice cap to spray sea water over the surface and replenish the sea ice."
Arctic ice management
http://onlinelibrary.wiley.com/doi/10.1002/2016EF000410/full
"As the Earth's climate has changed, Arctic sea ice extent has decreased drastically. It is likely that the late-summer Arctic will be ice-free as soon as the 2030s. This loss of sea ice represents one of the most severe positive feedbacks in the climate system, as sunlight that would otherwise be reflected by sea ice is absorbed by open ocean. It is unlikely that CO2 levels and mean temperatures can be decreased in time to prevent this loss, so restoring sea ice artificially is an imperative."
How a giant space umbrella could stop global warming
http://www.bbc.com/future/story/20160425-how-a-giant-space-umbrella-could-stop-global-warming
"The race to find a solution to a rapidly warming world is one of the most pressing challenges facing our planet. One proposal to try to halt this warming is literally out-of-this-world: a giant, space-based sunshade. We're already modifying our climate by accident, so why not do it by deliberate geoengineering? It's a radical idea, and it just might just work. Reducing the amount of light reaching our planet could cool the Earth quickly, even with rising carbon dioxide levels."

Journey to the Arctic - TechKnow

The Arctic is warming up at twice the rate of the rest of the globe. Summer sea ice has receded by almost 25 percent since 1979, with the sea change becoming ever more apparent and Arctic-native animals now visibly struggling in their prolonged search for shelter, ice and food.
Offshore oil exploration and increased tourism have also contributed to the speed at which environmental changes are occurring in the Arctic, with the fear of an ice-free summer on the horizon looming over the fate of the area.
These changes have also been spotted on land, with melting permafrost causing entire patches of land and man-made structures to sink as the earth softens.
Proximity to land and resources also presents a challenge, not only in times of emergency on the water, but also in executing the research required to understand and attempt to combat the effects of global warming on the Arctic. This is where the Polar-class icebreakers factor in.
The United States owns only two icebreakers that are able to breach the density of ice formations the Arctic is known for. Weighing it at 16,000 tonnes and with the abilitiy to reach 30,000 horsepower, they are a force to be reckoned with on the open seas.
These vessels are used not only as a coast guard, but also to aide in sceintific studies. Missions often include unmanned vehicles - a safety precaution - including drones and others that explore not only the view from the air, but also what is happening in the water and life under the ice.
Levels of carbon dioxide in the air and the sea, water salinity, temperature, oxygen and chlorophyll blooms - a potentially dangerous situation where algae multiplies and decomposes on the surface of the water, using up oxygen resources from the rest of the sealife - are all deliverables that can be quantified using the unmanned vehicles.
Scientists from the Arctic Domain Awarness Centre at the University of Alaska Anchorage are also working on an 'isotope sniffer' amongst other experiments and unmanned 'drones'. A snout hangs out from the bow of a Polar-class icebreaker as a means of atmospheric sampling, and feeds the information down to isotope analysers below deck, in seconds-long intervals.
The ultimate vision is to understand the effects of potentially environmentally-damaging activity, such as offshore rigging by the Shell oil company, creating technology that can accurately register important data in extreme temperatures and conditions - 'guardians' of the water - without endangering the lives of crew members.

http://en.wikipedia.org/wiki/Arctic
The Arctic (/ˈɑrktɪk/ or /ˈɑrtɪk/) is a polar region located at the northernmost part of the Earth. The Arctic consists of the Arctic Ocean and parts of Alaska (United States), Canada, Finland, Greenland (Denmark), Iceland, Norway, Russia, and Sweden. The Arctic region consists of a vast ocean with a seasonally varying ice cover, surrounded by treeless permafrost. The area can be defined as north of the Arctic Circle (66° 33'N), the approximate limit of the midnight sun and the polar night. Alternatively, it can be defined as the region where the average temperature for the warmest month (July) is below 10 °C (50 °F); the northernmost tree line roughly follows the isotherm at the boundary of this region.
Socially and politically, the Arctic region includes the northern territories of the eight Arctic states, although by natural science definitions much of this territory is considered subarctic. The Arctic region is a unique area among Earth's ecosystems. The cultures in the region and the Arctic indigenous peoples have adapted to its cold and extreme conditions. In recent years the extent of the sea ice has declined. Life in the Arctic includes organisms living in the ice, zooplankton and phytoplankton, fish and marine mammals, birds, land animals, plants and human societies...
The Arctic's climate is characterized by cold winters and cool summers. Precipitation mostly comes in the form of snow. The Arctic's annual precipitation is low, with most of the area receiving less than 50 cm (20 in). High winds often stir up snow, creating the illusion of continuous snowfall. Average winter temperatures can be as low as −40 °C (−40 °F), and the coldest recorded temperature is approximately −68 °C (−90 °F). Coastal Arctic climates are moderated by oceanic influences, having generally warmer temperatures and heavier snowfalls than the colder and drier interior areas. The Arctic is affected by current global warming, leading to Arctic sea ice shrinkage and Arctic methane release.
Due to the poleward migration of the planet's isotherms (about 35 mi (56 km) per decade during the past 30 years as a consequence of global warming), the Arctic region (as defined by tree line and temperature) is currently shrinking. Perhaps the most spectacular result of Arctic shrinkage is sea ice loss. There is a large variance in predictions of Arctic sea ice loss, with models showing near-complete to complete loss in September from 2040 to some time well beyond 2100. About half of the analyzed models show near-complete to complete sea ice loss in September by the year 2100...

In the Arctic Seas,
Francis MCCLINTOCK (1819 - 1907)
In 1857, Lady Jane Franklin, the wife of Sir John Franklin, who went missing with his entire crew during his 1845 expedition to discover the Northwest Passage, commissioned CaptainFrancis McClintock to investigate what had happened to the expedition, and purchased for him the small steam yacht known as the 'Fox'. This is McClintock's own account of the two year voyage of the 'Fox'. Following an initially unsuccessful attempt to cross the Davis Strait, the 'Fox' was forced to spend the first winter trapped in the sea-ice off the coast of Greenland. After the next year's thaw, McClintock eventually reached the islands of the Canadian Arctic, where an extensive search finally revealed the grisly truth of the fate of Franklin. (Summary by PatrickEaton)

The Military Sealift Command (MSC) is a United States Navy organization that controls most of the replenishment and military transport ships of the Navy. It first came into existence on 9 July 1949 when the Military Sea Transportation Service (MSTS) became solely responsible for the Department of Defense's ocean transport needs. The MSTS was renamed the Military Sealift Command in 1970.
Military Sealift Command ships are civilian manned, and are referred to be as being in service, rather than in commission. Some, owned by the United States government, have the prefix USNS, standing for United States Naval Ship, whilst others, on charter or equivalent, are simply the normal merchant MV, SS, or GTS. Their hull numbers have the prefix T- in addition to the normal hull number that an equivalent commissioned ship in the USN would have.
Four programs comprise Military Sealift Command: Sealift, Naval Fleet Auxiliary Force (NFAF), Special Mission, and Prepositioning. The Sealift program provides the bulk of the MSC's supply-carrying operation and operates tankers for fuel transport and dry-cargo ships that transport equipment, vehicles, helicopters, ammunition, and supplies. The NFAF's role is to directly replenish ships that are underway at sea, enabling them to deploy for long periods of time without having to come to port. The Special Mission program operates vessels for unique military and federal government tasks, such as submarine support and missile flight data collection and tracking. The Prepositioning program sustains the US military's forward presence strategy by deploying supply ships in key areas prior to actual need...

http://en.wikipedia.org/wiki/DEW_Line
The Distant Early Warning Line, also known as the DEW Line or Early WarningLine, was a system of radar stations in the far northern Arctic region of Canada, with additional stations along the North Coast and Aleutian Islands of Alaska, in addition to the Faroe Islands, Greenland, and Iceland. It was set up to detect incoming Soviet bombers during the Cold War, and provide early warning of a land based invasion.
The DEW Line was the northernmost and most capable of three radar lines in Canada and Alaska; the joint Canadian-US Pinetree Line ran from Newfoundland to Vancouver Island, and the Mid-Canada Line ran somewhat north of this...

http://en.wikipedia.org/wiki/Arctic_warfare
Arctic warfare or winter warfare is a term used to describe armed conflict that takes place in an exceptionally cold weather, usually in snowy and icy terrain, sometimes on ice-covered bodies of water. One must note the distinction between alpine and Arctic warfare - Arctic war does not always take place in mountainous terrain, and mountain warfare does not always take place in the cold.
The best recorded cold winter battles have taken place in northern and eastern Europe.
In 1242, the Teutonic Order lost the Battle of the Ice on Lake Peipus to Novgorod. In 1520, the decisive Battle of Bogesund between Sweden and Denmark occurred on the ice of lake Åsunden.
Sweden and Denmark fought several wars during the 16th and 17th centuries. As a great deal of Denmark consists of islands, it was usually safe from invasion, but in January 1658, most of the Danish waters froze. Charles X Gustav of Sweden led his army across the ice of the Belts to besiege Copenhagen. The war ended with the treaty of Roskilde, a treaty very favourable to the Swedish.
During the Great Northern War, Swedish kingCharles XII set off to invade Moscow, but was eventually defeated at the battle of Poltava after being weakened by cold weather and scorched earth tactics. Sweden suffered more casualties during the same war as Carl Gustaf Armfeldt with 6000 men tried to invade Trondheim, and 3000 of them died in a blizzard on a snowy mountain named Öjfjället.
During the Finnish War, the Russian army unexpectedly crossed the frozen Gulf of Bothnia from Finland to the Åland Islands and, by 19 March 1809, reached the Swedish shore within 70 km from the Swedish capital, Stockholm. This daring manoeuvre decided the outcome of the war.
Another famous example is the use of ski troops by the Finnish Army during the Winter War and the subsequent Continuation War, where the numerically dominant Soviet forces had a hard time fighting mobile ski soldiers.
In OperationBarbarossa in 1941, both Russian and German soldiers had to endure terrible conditions during the Russian winter. The German-Finnish joint offensive against Murmansk (Operation Silver Fox) in 1941 saw heavy fighting in the Arctic environment. Subsequently the Petsamo-Kirkenes Operation conducted by the Red Army against the Wehrmacht in 1944 in northern Finland and Norway drove the Germans out of there. In theLapland War, Finland turned against Nazi Germany under the Soviet Union's pressure, their former cobelligerents. While use of ski infantry was prolific in the Red Army, Germany formed only one division for movement on skis.
During Operation Zitronella in World War II, German and Allied troops fought over control of the island of Spitsbergen. This marks the highest latitude at which a land battle has ever been fought. However, given the extreme conditions, the German and Allied troops were at times compelled to assist each other to survive.
Operation Rösselsprung and Operation Wunderland were Arctic naval battles in World War II...
Arctic warfare is very dependent on equipment. For survival, troops need warm clothing and footwear, extra nutritious food, white camouflage, tents with sleeping bags, heaters and fuel.
Weapons can be fitted with an arctic trigger which permits firing while wearing heavy mittens.
Individual mobility can be increased by skis, cleats, and snowshoes.
Motorized vehicles are often unfit to stand freezing temperatures. Special procedures can be used to ensure they perform in the cold, such as running them continuously or starting them at regular intervals. Studded tires or tire chains are useful equipment for maintaining traction of wheeled vehicles. It is also possible to design special vehicles for operation specifically in arctic conditions, such as the Sisu Nasu, BvS 10, M29 Weasel or Aerosani...
